What is the value of 2/3(x -6) -y , when x= 9 and y=5/6?
ANTONII [103]

Answer:

Ã=7/6

Step-by-step explanation:

<em>2/3(x -6) -y </em>

<h3><em>put the value of x= 9 and y=5/6 </em></h3>

=2/3(9-6)-5/6

=2/3×3-5/6

=2/1-5/6

=12-5/6

=7/6

identify the amplitude and period of the function then graph the function and describe the graph of G as a transformation of the
mrs_skeptik [129]

Given the function:

g(x)=cos4x

Let's find the amplitude and period of the function.

Apply the general cosine function:

f(x)=Acos(bx+c)+d

Where A is the amplitude.

Comparing both functions, we have:

A = 1

b = 4

Hence, we have:

Amplitude, A = 1

To find the period, we have:

\frac{2\pi}{b}=\frac{2\pi}{4}=\frac{\pi}{2}

Therefore, the period is = π/2

The graph of the function is shown below:

The parent function of the given function is:

f(x)=cosx

Let's describe the transformation..

Apply the transformation rules for function.

We have:

The transformation that occured from f(x) = cosx to g(x) = cos4x using the rules of transformation can be said to be a horizontal compression.

ANSWER:

Amplitude = 1

Period = π/2

Transformation = horizontal compression.

What is the x-intercept of the graph of the function f(x)=x2-16x+64?
Katena32 [7]
X=8 

Explanation: 
f(x)=x^2-16x+64+(x-8)^2

You see there is a double x- intercept by the 8. So the parabola is tangent to the x axis. So x=8 f(x)=0 

hope this helps <span />
